Encapsulated transformer
This 1.5 kVA encapsulated transformer with a rugged NEMA 4X enclosure delivers robust isolation and voltage transformation for equipment in busy control panels. The enclosure protects coils from dust, moisture, and corrosion, reducing field failures and wear in harsh environments. For machine builders and panel makers, the unit simplifies specification and improves uptime, enabling faster commissioning and longer service intervals. The single‑phase design aligns with common 240/480 VAC supply rails and 120/240 VAC loads, minimizing wiring complexity and enabling straightforward integration into existing distribution circuits. Its 115°C rise rating supports dense installations and limited cooling, helping you achieve smaller enclosures without sacrificing performance. Documentation and support from Eaton—including catalog references and datasheets—facilitate compliant installation, spare parts planning, and predictable maintenance across the factory floor. This transformer also benefits from Eaton’s ecosystem, ensuring easier field support and component availability, which translates to lower total cost of ownership and reduced downtime across automation cabinets.

FAQs
The S20N11P16PCUSS4X is a 1.5 kVA encapsulated transformer designed for panel mounting in industrial control environments. Plan for a secure, vibration‑free mounting surface, allow adequate clearance for heat dissipation, and connect the 240/480 VAC primary to the appropriate supply while routing the 120/240 VAC secondary to the controlled loads. The NEMA 4X enclosure provides ingress protection against dust and moisture, reducing field maintenance. Verify mounting chassis compatibility with existing panels and ensure compliance with local electrical codes during installation.
A 1.5 kVA transformer can supply modest but steady power to multiple 120/240 V loads without overloading the secondary. This rating supports reliable operation of sensors, relays, and small motors in automation cabinets, especially when loads vary during startup or cycling. By maintaining a stable secondary voltage, equipment experiences fewer nuisance trips and improved control accuracy, which translates to higher overall line efficiency and reduced maintenance.
Yes. The unit uses a rugged encapsulated design with a NEMA 4X enclosure that protects internal windings from dust, water, and corrosion, making it suitable for harsh environments. While encapsulation aids reliability, always confirm site conditions and ensure proper cooling and secure mounting. For outdoor installations, consider weather protection strategies and routine inspections to sustain performance over time.
Certifications for this model are listed as 'Contact Manufacturer' in the provided data, so it is essential to confirm regulatory approvals with Eaton for your region. Typical industrial transformers may require CE markings for Europe, IP ratings for ingress protection, and SIL considerations for critical safety systems. Contact Eaton to obtain the exact certifications and compliance documents applicable to your installation and industry requirements.
Common use cases include powering control panels, automation cabinets, and machine control circuits in manufacturing lines. The 1.5 kVA, 1‑phase transformer provides isolated, stable secondary power for relays, PLC inputs, and human‑machine interfaces, enabling reliable startup sequences and consistent operation under varying loads. Its compact encapsulated design helps fit into tight panel spaces while delivering robust protection against environmental factors in factory settings.
